KH Director not giving me a dkh reading

ok, we see in the screenshot "alarm: range"

this means the KHD started to measure but it took too long to come to a reasonable measurement value

when does this happen?

a) reagent doesn't reach the KHD - check if reagent is pumped into the KHD during measuring and that there is no air pumped

b) dosing calibration values are incorrect, in this case KHD is not able to calculate correct amounts resp. a correct KH value - check if calibration and settings of all 3 KHD involved pumps are correct
post screenshots of these 3 pumps here

Reagent has no air in the tube and is reaching the Doser ok.
I will calibrate the Doser and try again.
Thanks

probe and waste pump shall have about 36 ... 37ml/min at speed 3
reagent pump approx. 4.5ml/min at speed 0

[Paullewis]

Pump 1 is 34ml/min
Pump 2 is 4.3ml/min
Pump 3 is 33ml/min

Still getting 0,0 and alarm error.

flow seem all a bit low to me, but this is not the reason for this behaviour

which speeds are selected? please post screenshots of all 3 pumps

another thought: you did calibrate the pH-electrode, and the calibration was fine at the end? you used fluids pH 4 and pH 7 in the right order?

[Matthias]

and please deactivate "alarm monitoring" until we found the reason for your issue, maybe there is also another message displayed in the status field

Pump 1 is 34ml/min

Pump 3 is 33ml/min

Still getting 0,0 and alarm error.

As I also have low values on some pumps, I tell myself that maybe the containers we use to measure the amount of water pump during calibration are not accurate or reliable. Maybe that it would be necessary to provide a reliable and calibratoed containers with Doser2 that guarantees the value of calibrations. As before, KH Director, it was not very important, but with the KH Director, it's very.
